Model Squama 2503R 140x25mm Reverse

Option 1 Pack

  • Reversed blades pull air in while facing forward
  • Hydro dynamic bearings run at 34 dB(A) for quiet cooling
  • 15 CFM airflow with 2.63 mm H₂O pressure
  • PWM control adjusts speed from 800 to 2400 RPM
  • Dual ARGB light loops sync via 5 V 3-pin header

Reversed-blade 140 mm fan

The Geometric Future Squama 2503R uses a reversed-blade design that presents the intake face forward. It fits standard 140 mm mounting points and connects via a 4-pin PWM header for speed control. A 5 V 3-pin addressable RGB header drives the dual light rings. White frame and blades suit light-themed builds.

Airflow and noise envelope

The fan spins between 800 and 2400 rpm, delivering up to 91.15 CFM of airflow and 2.63 mm H₂O static pressure. Maximum noise is rated at 34 dB(A). Hydro dynamic bearings support the speed range. The profile handles case ventilation and radiator duty, but very high-restriction radiators may exceed its pressure headroom.

PWM and ARGB integration

Speed is governed by the motherboard’s 4-pin PWM curve from 800 to 2400 rpm. Addressable RGB lighting requires a 5 V 3-pin header and compatible software for per-LED effects. Builds without a 5 V ARGB header cannot use the lighting. The 25 mm thickness fits most 140 mm locations.

Spurningar um þessa vöru

Will the 140mm frame and 4-pin PWM connector fit the radiator and header I already use?

The fan uses a standard 140mm square frame and a 4-pin PWM connector, so it mounts on any 140mm radiator or case point and plugs directly into a motherboard PWM header.

How can I confirm the dual light loop is syncing correctly after installation?

Connect the 5V 3-pin ARGB lead to a compatible motherboard header, then use the board’s RGB software — the two rings should display the same effect simultaneously if sync is active.

Does the single pack include mounting screws and the ARGB cable, or must I buy them separately?

The 1-pack ships with mounting screws and the 5V 3-pin ARGB cable attached; no extra parts are required for installation.
